I have 3 servers with dual nic 10gb card. can i connect them directly with cross cable without the need of switch and they will be able to ping each other in same network?
I want to create a vmotion virtual switch in ESXi and put both port, will ESXi find how to get each of the servers by the right interface?
Server A (10.0.0.1)
port1 -> Server B
port2 -> Server C
Server B (10.0.0.2)
port1-> Server A
port 2-> Server C
Server C (10.0.0.3)
port1-> Server A
port2-> Server B

I’d be wary of loops with your setup to be honest. Wouldn’t it be possible to have server A go to B, B to C, and switch both interfaces of B in the same vswitch? Ngl I’m not that knowledgeable about esxi.
I’ve done this before without any loop issues.
I tried something similar one time but not on ESXi. Two ports can’t have the same IP address so I created an /etc/hosts file so each host knew about the other based on hostname and not ip address.
Make the 10.0.0._ addresses loopback addresses, and do point-to-point connections from each box to every other box. No idea how to do this in ESXi, but it’s straightforward in *nix/BSD.
You wouldn’t need a crossover cable. 10G ports, as with most/all others these days, are auto-MDIX. They know when they should be in crossover mode and switch automatically.
I prefer using separate subnets for different network adapters. In any case, create vswitch and vmkernel for each network port and configure IPs.
